Note 395 — Chapter XXII · VOLCANOES OF THE UPPER OLD RED SANDSTONE—THE SOUTH-WEST OF IRELAND, THE NORTH OF SCOTLAND
Reading edition
There may be some other examples of Upper Old Red Sandstone volcanic rocks in Ireland which I have not yet been able personally to examine. On the maps of the Geological Survey (Sheet 198, and Explanation, pp. 8, 17) contemporaneous rocks of this age are marked as occurring at Cod's Head and Dursey Island, on the south side of the mouth of the Kenmare estuary.
